33.5 is 2/3 of the 1 p.m. temperature
multiply 33.5 by 3/2 to get 50.25 at 1 p.m
at 10 a.m. it was 8.7 degrees warmer, or 58.95 degrees.
The value of the temperature is what is being asked for. The true temperature requires the Kelvin scale but that is a non-math issue.

As you formulate the problem,  it is  VERY  ILLITERATE  description to say that one  Fahrenheit temperature
is  1/3  of the other  Fahrenheit temperature.


This way to describe temperature is  NEVER  USED  and is considered as a  BAD  STYLE  wording.


And when a person writes or pronounces it,  it becomes clear to everybody around, that the person
is unfamiliar with using correct terminology.
